To Grandmother's House We Go

"Do we have everything?" Dad asks from the front seat of the car. "Luggage?"Aiden turns around to look over the back seat into the cargo area, seeing four bags for the four people in the vehicle. "Check", he calls. "Snacks, drinks?" Aidan rummages in a sack on the floor between him and his sister, Hailey, finding some crackers, cookies and protein bars along with several bottles of water and tea. "Check." "Toys?" asks his mother, Emily. Her son moves one sack over and counts five vibrators, four butt plugs, a family-size jug of lube and assorted miscellaneous accessories. "Should be enough to get by for a week," he answers. "Chargers?" Mom asks with concern. He checks again. "For most of them at least. And a travel adaptor." Emily considers briefly, "I'll take the adaptor and the big wand right now, " she decides. Aidan passes the large device up to his mother.

"Ok, let's go see your grandparents!" Dad says with paternal enthusiasm as he backs the car out of the driveway and begins the four-hour drive. Emily has her large vibrator blasting her bare hairless vulva before they're even on the highway, her legs spread wide in the front passenger seat, her pretty green sundress hiked up to her waist. Dad is bottomless, in preparation for the copious road head to come, his massive cock hanging limp between his legs, unresponsive to the utterly mundane situation of having his wife masturbating in the seat next to him while he drives the family around. Aidan's wearing shorts and a black concert t-shirt, updating his socials to inform his few hometown summer friends that he'll be unavailable for the week. His sister, next to him, is completely naked as usual, while doing likewise on her own phone.

They've barely left their neighborhood when Hailey reaches over and starts squeezing Aidan's soft cock through his shorts. "Want to fuck my ass?" she asks almost indifferently. "Warm me up a bit?" Aiden responds, removing his shorts. Still scrolling on her phone, Hailey reaches over and gives him a lazy handjob for the next few miles until her brother is rock hard, then puts her phone down and twists herself across the car's backseat to start licking Aidan's cock. After wetting Aidan's prick thoroughly with her tongue, Hailey starts working her head down over his sizable length. The sloppy noises that slip out as she transitions to a deep throat head-bobbing alert their mother, who is at this point getting rather close to her climax. Emily shifts around and rests her head on the shoulder of her seat to watch her children's incestuous play, still keeping the bulky corded wand glued to her clit. Dad notices his wife's attention and and adjusts the rearview mirror to keep an eye on the show himself.

His cock hard and lubricated, Hailey allows her brother a few precious moments thrusting up into her esophagus before flipping around sticking her ass up at him in the middle of the bench seat, resting on her elbows. Aidan crouches behind his father's seat and lines his raging dick up with his sister's brightly shining asshole. Once again, he's reflects on how grateful he is that that his whole family got the gene for anal self-lubrication, even the men, who get a lot of prostate attention as a result. Holding himself up by the backrest of the seat, Aidan slowly drives his full seven inches into Hailey's tiny anus. Bottoming out, he takes a minute to just enjoy the loose warmth of her deep colon around his cockhead while her stretched sphincter grips his base tightly.

The car stops for a red light at a small town intersection as Aidan soaks in his sister's intestines. One lane over, directly in Aidan's line of sight is a sheriff's SUV whose driving officer has pulled up short after noticing the action in their car. A tap on his sister's back causes her to sit up and see the policeman, her small conical tits dangling. She tosses the uniformed man a flirty head nod as her brother starts fucking her ass in a reserved tempo. Out the window, the officer tips his wide-brimmed hat in acknowledgement and returns his attention to the stoplight after a few more moments of admiring the nude young woman. Then the light changes and the sheriff's car turns right at the intersection, away from their course.

Emily is panting hard now, watching her son's cock dragging her daughter's pink asshole outward with each slow stroke. As her climax begins, she starts to wail loudly before catching herself and shoving the side of her hand into her mouth to avoid deafening everyone else in the car, but her convulsions against the seat jiggle them all slightly. Immediately after the last wave passes, she drops the vibrator and throws herself into Dad's lap, stuffing his soft but rising erection entirely into her mouth and holds him there as his expanding member forces its way into her throat, playing with Dad's balls while she waits. Once his prick reaches as far towards her stomach as it can get, Emily begins a rather aggressive blowjob. Mom's always hungry for jizz right after coming, Aidan is well aware.

Closing in on an orgasm a few more miles down the highway, Dad pulls the car over for safety at a gas station, right in front of the shop entrance. He rolls the windows down, puts the seat back a bit and rests his hand on the back of Mom's head. Emily takes the encouragement and sinks onto him completely, nuzzling his pubic hair with her nose and flexing her throat muscles around his cock. Meanwhile, Aidan takes advantage of their parked situation to start reaming Hailey's ass properly, with a hand on each hip, shaking the car side-to-side noticeably. An older couple leaving the gas station notices the motion as they walk past the car, stopping and watching respectfully just beyond the open windows. Visibly in their early 50s, the female of the pair reaches into her companion's pants with one hand and obviously starts massaging him as she lifts her skirt and shows Aidan a neatly trimmed grey-brown bush over a large clit that she starts rubbing publicly.

Aidan, having both the incredible sensation of his sister's asshole and the unexpected visual aid provided by the friendly strangers, comes almost immediately, pumping several large bursts of hot semen into his sisters rectum. Only recently having obtained a vibe from the travel collection, Hailey grunts with pleasure at the sudden fullness, but is still working up to her own climax. Taking the opportunity while they're still parked, Aidan pulls out of his sister and hops out of the car sans pants to head inside the store. Over his shoulder he can see the older gentleman has started fucking his partner from behind as they watch his mother's oral work.

He's back a minute later, with an empty cup of ice from the drink section and a soda for himself. Standing outside the passenger side he makes a suggestion, "Hailey could use you in the back, Dad - I brought this for her and Mom" indicating the empty cup with a motion. Everyone understands his intent from experience, Hailey taking the glass and squatting on the seat to push Aidan's jizz out of her and onto the cupped ice with her bowel muscles. His mother and father part, saliva dripping from her mouth before it's wiped away on a wrist. Dad exits the driver's seat and moves back to Aidan's former spot while Mom slides over to replace him and finally Aidan takes shotgun, clicking his seatbelt together just as Hailey's tan wrist shoots forward holding the now half-full cup of iced cum. Emily grabs the drink from her daughter's hand with an excited noise and immediately takes a long gulp of her son's anally-infused seed.

After releasing the requisite cheesy "Ahhh!" at her refreshing beverage, Mom pulls the car away from the curb while Dad starts fucking his daughter in a sort of crouched-cowgirl style, cramped against the back of the driver's seat. Aidan waves goodbye to the voyeur couple as the car backs out, the female of the pair holding herself up on a handicapped parking sign while her partner pounds against her asschecks. They both wave back. And so the drive goes, with Mom and Dad switching off at the wheel and front seat swapping with back so that every pairing gets turns together in the backseat.

Hours pass this way as they drive towards Grandma and Grandpa's house, the men feeding on the snacks and the women feeding from their cocks in turn. By the time they pull into the driveway of Emily's parents' house, Aidan and his father have each come nearly a dozen times. Towards the end of the drive, Mom insisted that she and Hailey needed to save room because Grandma would insist on feeding everyone as soon as they arrived and so the gas station drink cup in the center console stands completely full of the Aiden and Dad's combined emissions when the car comes to a stop in front of the old colonial house Mom grew up in.

Grandma and Grandpa are walking out to the car before they all even get their feet on the ground. "Hello! Hello! There's my beautiful grandchildren!" Grandma crows. She's still in fine form in her early 70s, aging being very manageable in this modern era of genetic wizardry. Her skin shows the wrinkles of age but she still has a smooth complexion and her long grey hair is silky. Tight athletic clothes flatter her slim figure as she reaches out to grab Aidan's face and pull him into several cheek kisses that segue into her tongue probing the back of his mouth.

Grandpa has aged no less well, looking handsome with white hair and beard and his formerly well-muscled build still in fighting form. "How are my girls?" he roars out, grabbing Emily into a hug with one arm while running his other hand up her skirt and mashing her bare asscheck with his massive leathery paw. Mom giggles and kisses all over his face and neck, instantly returned to being her daddy's girl even in her middle age. Hugs are released and everyone rotates, Grandma giving her son-in-law's cock a welcoming squeeze while Grandpa fondles his granddaughter's breasts and remarks with praise on her development.

Father and son turn to unload the car while keeping up the small talk. "Well, I hope all you saved room for supper!" Grandma declares in a lull. "Of course we did, mom" Emily replies to her mother with slight exasperation and an eye roll. Grandma gives her daughter a suspiciously sly look, "Good, good... so then there must be a cup of cum in that car with my name on it?"
